ROOF-FLASHING.

To all whom it may concern: 7 Be it known that I, PETER F. MoOArrRnY,

a citizen of the United States, residing at Spokane, in the county of Spokane and State of Washington, have invented a new and useful Roof-Flashing, of which the following is a specification.

This invention relates to roof flashings particularly designed for usein connection withvent pipes. It is well known to those skilled in the art that the swaying of a Vent pipe soon breaks the connection between the j pipe and the ordinary flashing employed, with the result that leaks occur and constant repairing is necessary.

One of the objects of the present invention is to provide a flashing which permits movement of the vent pipe without breaking the connection between the pipe and the flashing or producing leaks.

A further object is to provide simple means for connecting the vent pipe to the flashing and which connection will require practically no attention after having been once applied. a

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention. I

In the accompanying drawings the prehas been shown.

In said drawings: a Figure 1 is a side elevation of'a portion of a vent pipe having the present improvements combined therewith.

Fig. 2 is a vertical section through the flashing and the connection between it and the vent pipe.

Fig. 3 is a plan view of the structure shown in Fig. 1.

Referring to the figures by characters of reference 1 designates'a portion of a roof from which extends a frusto-conical flashing 2. A vent pipe 3 is adapted to extend through the flashing, the upper or small end of the flashing fitting snugly about the vent Specification of Letters Patent.

duced portion 5 at the center thereof is slipped downwardly onto the pipe. The

reduced portion. 5 is designed to slidably engage the pipe, while the end portionsof V the sleeve are concentric with but spaced Thus when the sleeve is I from the pipe. moved downwardly on the pipe the lower extremity thereof will receive the upper end of the flashing as shown in Fig. 2 and wedge tightly thereon. After the parts have thus been positioned the space. between the pipe and the upper portion of the sleeve 4: is filled with oakum or other if packing material indicated at 6 and upon which is poured a layer of lead 7 or the like.

Thus the parts are held properly assem' bled and, obviously, should the Vent pipe 3 sway relative to the roof structure 1, no,

break would occur at the connection be tween the flashing and the vent pipe but, instead, the lower portion of the sleeve and'prevent leakage.

What is claimed is g I p The combination with a tubular flashing taperedupwardly, and a vent pipe extends ing through and fitting snugly within the rewould at all times constitute a water shed duced end of the flashing, of a cylindrical sleeve having a central annular reduced portion the internal diameter of which equals the external diameter of the vent pipe, said reduced portion being curved transversely, thereby to diverge upwardly and downwardly from the vent pipe, one.

end portion of the sleeve housing and litvtmgsnugly upon the upper portion of the flashing, and a packing within the other and surrounding a end portion of the sleeve the vent pipe, the lower portion ofthe packing being wedged between the vent pipe I and the upper portion of the reduced annular portion of the sleeve, thereby to seal the joint between the vent pipe and sleeve. 7

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
